Hey all, been following this case closely, haven't posted much. Anyway, going on the evidence/info we currently have, to me, this seems like a stranger abduction. Most likely two stranger abduction. Here is what I believe is the most plausible scenario (certainly many many more situations and scenarios are possible or even likely, but to me, this seems most likely)
Sierra walked to the end of her driveway with her purse and phone. Her spare clothes were in her bag for an innocent reason i.e. going to an activity after school, out with a friend, sleepover etc. If the scent dogs are accurate and her trail ended at the driveway, it stands to reason her abductors forced her into a vehicle and drove off. One person driving, one holding her down and then throwing her phone and purse out the window. I believe the abductor or abductors did not know Sierra, but are in the area often for a reason. Maybe they've seen her a few times and figured the timing was just right, or maybe they planned it. But they are in the area often. (Cableman, construction, farmer, etc)
I can easily poke holes in my theory, so I am always open to hearing new and fresh ideas and insights. And praying for a happy outcome
